IMPRQVEMENT iN SASH-HOLDERS.

I, PHILo B. HovnY, of the town and county of New London, State of Connecticut, have invented certain Improvement-s in irVindow-Fastenin gs, of which the following is a specification.

This invention relatesto that class of fasteniugs which is provided with an inclosing-case, and is attached to the flaming of the sash to be supported, the support being derived from the friction of fastening against the casing or framing surrounding the win-` dow or their equivalent.

In the drawing accompanying and forming apart of.,

this specification are given several Views illustrating lmy improvement.

In all drawings like letters refer to like parts. A represents the inclosing-case. B is a shoe or stop,provided with a thumb-pice,

.11), for moving it from the outside of the case.

The Schedule referred to in these Letters Patent and making part of the same.

and released from the hand, it is then prevented from descending by the operation of the fastening.

The spring G raises the stop B b'y its action on the part E, and presses it firmly against the casing. By the aid of friction the connecting part E is brought to bear with great force against it, and the sash is held suspended.

To lower the sash the thumb-piece is pressed down, which relieves the-'pressure of the stop B, and the sash is lowered by hand.

AtC in the stop B is inserted a piece of India rubber or other elastic substance. This may be inserted into a recess, as shown, or attached in any suitable manner.

The surface of this elastic piece may be either smooth or corrugated.

The fastening may be used either with or without this part. It is believed, however, that it will be found to add much to its efficiency.

I claim- The combination of the friction-stop B, pivoted tov forced upward by the spring G, the stop B being released from the window-trame by depressing the thumbv piece, all the parts being arranged as and for the purposes set forth.
